Filtrete - 16 in. W X 20 in. H X 4 in. D Polypropylene 1550 MPR Pleated Air Filter 1 pk

This deep‑pleat air filter is designed for whole‑home HVAC media cabinets and helps improve indoor air quality by capturing particles as air circulates through the system. Its electrostatically charged polypropylene media, rated at 1550 MPR (approximately MERV 12), targets fine particles such as smoke, cough and sneeze droplets, and airborne bacteria and virus‑carrying particles, along with common household contaminants like dust, lint, pollen, pet dander, mold spores, and dust‑mite debris.
